pyIRSF-2.2 released

• Sigma clipping using M.A.D.(median absolute deviation) is adopted for the combining process of registered images.
• You can select either the conventional IRAF's imcombine or the new combine program with the M.A.D. clipping.
• polmode is automatically selected when you execute sirpol.py set.
• A parameter 'geotran.interpolation' has been changed to 'drizzle' in registration.dotran()
  • It was 'drizzle[0.5]', which could yeild a poorer spatial accuracy < 0.25 pixels at most.
• Two new scripts have been added.
  • twflatview2pdf.py : This script writes the output of twflatview.py to a PDF file with 12 outputs per page.
  • subregionview.py : A selected square region of a combined image for all precombined image is written to a PDF file.
